LTM 1060-3.1

Variable steering concept

Active rear axle steering

The rear axles are actively electro-hydraulically controlled in accordance with

the speed and steering angle of the front axle. Five different steering pro-

grammes (P) can be selected by touch button.

• Remarkably reduced tyre wear

• Improved manoeuvrability

• Stable driving condition even at high speeds

• All three axles can be steered

High safety standards –

entire know-how from Liebherr

• Centring cylinder for automatic straightening of rear axles in case of failure

• Two independent hydraulic circuits with wheel and engine driven hydraulic pump

• Two independent control computers

P1 Road steering

The axle 1 is mechanically steered by the

steering wheel. The axle 3 is actively steered

depending on the speed and on the steering

angle of the 1st axle. Above 30 km/h it will be

adjusted to straight driving and ﬁxed.

P2 All-wheel steering

The axles 2 and 3 are turned by the steering

wheel depending on the steering angle of the

1st axle to provide for the smallest turning

radius.

P3 Crab steering

The axles 2 and 3 are turned by the steering

wheel to the same direction as the steering

position of axle 1.

P4 Reduced swing out

The axles 2 and 3 are turned depending on

the wheel turn of the 1st axle to minimize the

back swing of the rear of the chassis.

P5 Independent rear axle steering

The axle 1 is steered by the steering wheel,

the axles 2 and 3 are steered by push buttons

independently from the steering angle of the

axle 1.
